I bought this second hand on eBay, and have teamed it up with my beloved ﻿Nexus 5﻿. Its a brilliant thing! You just put the phone on top of it, feel the magnets position it in the right spot, and it makes a sound effect so you know its charging, and thats it! No messing about with wires. I've also got the LG QuickCover for my phone, which is compatible with the wireless charger, so I don't even need to remove it from the case to charge.

There's a second advantage, if you unplug the mini-usb cable from the wireless charger itself, and plug it straight into the phone, you get a turbo charger that charges at about 1600 amps instead of about 700 amps. Like that, the phone will charge fully from empty in about an hour. It is also exactly the same as the separately available official Nexus Charging Accessory.
